Answer #1

Thank you...!!!

Please do not forgot to like.

Consider the following
data set:
Find the lower
fence
Find the upper fence
Number of outliers =
40.9
39.4
38.8

31.4
29.3
34.4
Using the IQR definition of outliers, how many outliers are in this
data set?

Determine if there are any outliers in the data. If so, indicate
each outlier with an ordered pair. If not, write "none."

18 ) Five numbers are given: (5, 10, 15, 5, 15). Now,
what would be the sum of deviations of individual data points from
their mean?
A) 10
B)25
C) 50
D) 0

12) The following data values represent the
number of work hours per week for a sample of college students
during the previous spring semester.
30, 17, 16, 20, 14, 28, 18, 17, 29, 14, 20, 29, 36, 69, 16, 20,

Measures of Center & Outliers
The following are the weights of a sample of female high school
students:
08 |8
09 | 5 2 0 9
10 | 4 9 3
11 | 5 9 8 3
12 | 3 9 7 7 6
14 | 0 6 3
15 | 4 1 7 2
18 | 5
This table, for example, indicates that one female weighs 88 pounds
and that no female students weigh between 130 and 139 pounds....

{58, 56, 87, 17, 32, 14, 30, 75, 44}
3. Identify any outliers in the data set and list them here.
Explain why they qualify as outliers or, if none, explain the
reasoning for concluding there are no outliers.
4. Create a frequency table for the data from question 1 with
five classes. Show the upper and lower limits of each class and the
frequency associated with each class.
5. Create a steam and leaf plot for the data. On...

Provide an appropriate response. Use the data to identify any
outliers.
16 27 1 32 15
5 18 9 20 14
17 19 16 10 21
28 14 36 18

e) the scores required to be either mild or extreme outliers;
identify if your data has any outliers and if so, what type . And
find the z scores associated with the highest and the lowest data
value .(Show all work for this part. Your work can
either be handwritten or typed.)
